0.16 g of methane was subjected to combustion at `27^(@)C` in a bomb calorimeter. The temperature of Calorimeter system (including water) was found to rise by `0.5^(@)C`. Calculate the heat of combustion of methane at
(i) constant volume (ii) constant pressure.
The thermal capacity of Calorimater system is `17.7" kJ K"^(-1)`. `(R=8.313" J mol"^(-1) K^(-1))`
